Apache Tomcat URL mask/redirect

My company has purchased a system that uses Apache Tomcat, but I do not have any experience with Tomcat. What I am trying to do is mask/redirect a URL from http://localhost:8080/somefile to http://www.myurl.com. Is this possible to do with Tomcat and how can it be done?

Who is Participating?

It can done by the apache configuration if the webserver is answering 172.0.0.1:8080. Is somefile is a specific URL or a code name for unknown URLs list ?

I in most case prefer the HTML redirect and not the pure HTTP 3XX (e.g 304) level and do it by meta tag or JavaScript (or both) as it give me more control over the process and I cant put statistical code on the pages.

Any request from localhost (and any port , but this is less importent) is answered by your own computer (this is why is called local-host). Apache has noting to do with it. Remote server is not requested to answer that call because it does not get it.
You can, however, make a change of each computer that need to access it by altering .host file to make this redirect. Keep in mind this is very unlikelly

I forgot to add this part,
In order to redirect you will need to change apaches config (i.e httpd.conf file) and add a block like this:
<virtualhost 172.0.01:8080>
Redirect /somefile http://www.myurl.com
</virtualhost>
